TJAM51,
Using LT2004 + LTE, no drama upon loading pm or PlMatchWidth. I doubt the problem is LT [yes there were problems with plines in 2000], but 2004 & 2002 are similar - besides the obvious. I'd suspect LTE version you are using. I have not bothered installing latest one, so still using the Jan. 06 one and no probs when loading.
As for running the routines, pm does nothing and 2nd one displays error message! Do not have time for more investigating.
HTH
